Idaho Code § 6-1201

Every year, in rapidly increasing numbers, the inhabitants of the state of Idaho and nonresidents are enjoying the recreational value of Idaho’s mountains, rivers, and streams, many of which are remote and far removed for ordinary auto travel. The tourist trade is of vital importance to the state of Idaho, and the services offered by licensed outfitters and guides significantly contribute to the economy of the state of Idaho. The legislature recognizes that there are inherent risks in the recreational activities provided by outfitters which should be understood by each participant. These risks are essentially impossible to eliminate by outfitters and guides. It is the purpose of this chapter to define those areas of responsibility and affirmative acts for which outfitters and guides shall be liable for loss, damage, or injury, and to define those risks which the participant expressly assumes and for which there can be no recovery.
